Featured below are companies that have experienced recent insider buying and selling activity in the public market through their direct and indirect ownerships.

Keep in mind, when looking at transaction activities by insiders, purchasing activity may reflect perceived value in a security. Selling activity may or may not be related to a stock's valuation; perhaps an insider needs to raise money for personal reasons. An insider's total holdings should be considered because a sale may, in context, be insignificant if this person has a large remaining position in the company. I tend to put great weight on insider transaction activity when I see multiple insiders trading a company's shares or units.

On June 14, board member Diane Nyisztor doubled her ownership position with the purchase of 1,000 shares at an average price per share of $41.93, increasing her portfolio's position to 2,000 shares.

Last week, we reported that three insiders were buyers in the market.

In a relatively small trade, on June 7, Carl Colizza, president and chief operating officer of the Canadian dairy division, purchased 690 shares priced at over $43 per share. This transaction lifted his portfolio's holdings to 13,901 shares.

The prior day, Annalise King, who sits on the board of directors, accumulated 3,000 shares, initiating a portfolio position, and fellow board member Annette Verschuren purchased 1,000 shares at an average cost of $43.03 per share, raising her portfolio's holdings to 8,000 shares.
